Expressway buffer pressure relief guide protective fence and installation method thereof
The invention relates to the technical field of highway safety protection facilities, and discloses an expressway buffering pressure relief guide protective guard and an installation method thereof.The expressway buffering pressure relief guide protective guard comprises stand columns and a protective guard body, the protective guard body and the stand columns are connected through longitudinal buffering pressure relief assemblies, and fixing holes and transverse pressure relief grooves are formed in the ends of the protective guard body; the fixing holes and the transverse pressure relief grooves in the end parts of the adjacent guardrails coincide and are correspondingly provided with connecting pieces; the longitudinal buffer pressure relief assembly comprises an inner occlusion prevention block and an outer occlusion prevention block which are oppositely arranged, the two occlusion prevention blocks are matched through a plurality of connecting screw rods, springs are arranged on the connecting screw rods, the two ends of the springs abut against the occlusion prevention blocks, and the outer occlusion prevention block is fixedly connected with the guardrail through the connecting screw rods; after the guardrail is suddenly and severely impacted, instantaneous yielding force unloading buffering occurs in the transverse direction and the longitudinal direction, and therefore rigid impact damage caused by the guardrail and a vehicle is reduced.
本发明涉及公路安全防护设施技术领域，公开了一种高速公路缓冲卸压导向防护栏及其安装方法，包括立柱和护栏，护栏与立柱之间通过纵向缓冲卸压组件连接，护栏端部设有固定孔和横向卸压槽，相邻护栏端部的固定孔和横向卸压槽重合并对应安装连接件；纵向缓冲卸压组件包括相对设置的内咬合防阻块和外咬合防阻块，两个咬合防阻块之间通过若干连接螺杆配合，连接螺杆上设有弹簧，弹簧两端与咬合防阻块抵接，外咬合防阻块与护栏通过连接螺杆固定连接；在护栏受到突然巨大撞击后，横向和纵向方向发生瞬时的退让卸力缓冲，从而减少护栏与车辆造成的刚性撞击破坏。
